If there is a sign on a cliff top “do not jump off the edge, as to do so could result in death”, it is not a threat or punishment, it is merely good advice and fair warning of the consequences. People are free to weigh that up, and choose to jump, or not, or even argue the toss, if an argument is what they enjoy. The sign is a good idea though, don’t you think? Especially in this litigious age : “oooh, I’ve jumped off the cliff and died, that’s your fault for not warning me, I’m going to sue!”. Oh yeah? Well, good luck with that ‘cos you’re dead.
I don’t see anyone using ‘religion’ as a threat, nor a punishment. 🤷 I do, however, see some folk seemingly overly concerned over their perception that they are being threatened. If statements of not believing in ‘sin’ and claiming a blameless life, and being totally unworried about the future are absolutely without a shadow of a doubt certain, with not one chink of ‘what if …’, then rock on.
Re your thought about Jesus, there are other opinions available. For me, my terms of reference are my Bible and my lived experience, and I declare that Christ Jesus is exactly who He said He is, and who my Bible says He is: Light of the World, Lord of Lords, King of Kings, I AM. He is my strength, my Rock and my Redeemer. He came to set the captives free, and in Him I am free indeed. All praise and glory to God.
Again, returning to the subject of the thread, and has already been documented, every eye will see the day that Christ returns - there will be no doubts.
